unknown user name or bad password

Samba - jcifs mailing list

I gotten past this issue, I think.  I now get:  jcifs.smb.SmbAuthException: Logon failure: unknown user name or bad password.


I am trying to hit a Windows folder from another Windows machine.  The credentials are correct and the target folder is set to Sharing and my userid is on the list.


Not sure how to debug this.

Subject: [EXTERNAL] - [jcifs] network name not found


I am getting started with jcifs.  I am hitting what seems to be a newbie issue.  jcifs.smb.SmbException: The network name cannot be found.

I am starting off with a hello world based on the Example – List.java


There seems to be many ways to initialize the SmbFile.  I am having trouble determining if its my SmbFile or environment issue on the host I am trying to hit.

My context:


List files on a shared folder.  The folder has been set to Shared for my user id.  The Network path is \\SPWV01\Servers .  The target machine is a VM running Windows Server 2012.


I tried this, but I get the error above.


NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("mydomain", "mysuser", "mypw");

String sPath = "smb://target IP/SPWV01/Servers/";

SmbFile file = new SmbFile(sPath, auth);


I have tried the fully qualified host name first and then tried the IP address.


Thanks in advance.
